The I/O modules themselves have 2 pin headers with 14 pins each. The pin headers receive adapters with wire terminals. The adapters are included. The German I/O module page has an animation which shows this in detail, it seems the English page is missing that for some reason: https://revolution.kunbus.de/io-modul/ https://revolution.kunbus.de/io-modul/

That's great. Are there any modules with support for camera and/or screen (HDMI/DSI) planned?

  A mini HDMI port is on the top of the RevPi Core and you can attach any display that you would normally use on a Raspberry Pi. There are some displays available from 3rd parties which are suitable for mounting on top hat rails. The CSI and DSI pins are not accessible on external ports I'm afraid. I'm also not aware of plans to add modules which would make CSI/DSI available externally. In theory it's possible to open the case and attach wires to the pins which go to a connector external to the case and you could connect a CSI camera or DSI display there, however the result can hardly be considered "industrial". :-) An alternative is to connect a USB camera. The 4-core BCM2837 on the Compute Module 3 is beefy enough for image processing with OpenCV, in fact we're using OpenCV for our demos at expos. It may even be sufficient for video transcoding. One thing to be aware of though is that we're using a kernel with RT patches. Which means low latency, but also lower throughput. If you don't need low latencies but maximum throughput, it may be a good idea to use a kernel without RT patches. All the tooling to build a custom kernel is on GitHub.

  We are already testing the next generation of RevPi which is called "RevPi compact". This series will have a connector with the DCI for the original Raspi camera. We will start selling them at SPS Drives Fair in November. But there is plenty of really good USB cameras on the market and they work fine with Compute Module 3 (CM3). We have had an exhibit at Hannover Fair where the only sensor was an USB Cam connected to the RevPi Core which controlled pumps and valves to mix oil and water from 2 tanks into a third tank and separate the fluid back in their tanks again using just the color difference of the fluids to detect the fluid levels.

    Hannover fair this year? Damn, I skipped this one, would have been great to chat with you. I am actually working on a prototype of something similar- Pi, camera, small touchscreen, distance sensor and small number of IOs. The two specific use cases for me: measure dimensions of parts hard to measure with other sensors and stopping conveyor when some parts end up in unexpected places.
